Shipping seven Kotlin Multiplatform projects on a fully custom local harness

Not vibe coding: a custom harness on a patched llama.cpp build has shipped seven real KMP projects.

This person shipped seven Kotlin Multiplatform projects since setting up a local inference server, and is clear that it wasn't vibe coding — the harness is fully custom, running a llama.cpp build with several hand-picked patches. Their take is that most developers don't actually need frontier-tier models for this kind of work.
